To (alt wwnt 77mg/ concer/t:

Be itknown thatl, GUsTAvE WENZELMANN, a citizen of the United States, and a resident ot Missal, in the county of Livingston and State of Illinois, have invented certain new and useful Improvements in Elevators and Dumps, of which the following is a specifications.

My in vcntion relates especially to elevators for storin gand handling grain,although some of the devices herein claimed may be used upon other forms of elevators and for storing and handling other commodities than grain.

The invention consists generally in spe cial combinations and arrangements of parts whereby the loaded wagon may be driven through a central longitudinal passage beneath the storage-bin, the contents unloaded into a dumping-car by a tilting floor-beam and grain-shicld to be connected in. a novel manner with and to be raised and lowered upon an elevator-cage by means of the grainwagon and team when the latter is driven from the elevator, the car being adapted to move upon eitherof two tracks placed at right angles one to the other and dumped into any one of a series ot bins suit-ably arranged either for a single ora double elevator either carried at right angles to a storage-bin or dumped directly 'from the elevator-car into a railroad graincar outside the building, a novel mechanism for placing and steadyin g the car upon the elevator-cage, for weighing the car independently of the cage, for closing, locking, and releasing the doors of the dumping-car, for moving the car to any position upon the upper or dumping licor from one side or from the other side of the elevator; and my invention further consists in certain other devices involving details oi" construction particularly hereinafter described and claimed.

In the accompanying drawings, Figure l is a horizontal sectional pla-n ot my improved elevator in line .r :n of Fig. 2; Fig. 2, a een tral longitudinal section thereof with the elevator-ear at the bottom of the shaft while being loaded. Fig. 3 is a transverse vertical section in line y y ot Fig. 2, showing a singleelevator system; Fig. et, a similar view of a double-elevator system in the same line of section; Fig. 5, an enlarged elevation of the winding mechanism for the elevator-cage;

Fig. (3, a similar plan View thereof; Fig, 7, an enlarged perspective ot a safety raok-bar hinged to the elevator guide-rails; Fig. S, a perspective view of a detachable grip at the end of the hoisting-cable to be attached to the wagon; Fig. 9, a perspective view of an 4elevator-car, and Fig. l0 a longitudinal elevation thereof with the grain-doors open; Fig. ll, an end elevation of a car on the elevated transverse track with the grain-doors open; Fig. l2, a plan of a car, showing the double cable-carrier connections; Fig. 13, a longitudinal section thereof, showing one Set of cable-carrier connections and the lower part of the elevator-cage with one ot the sidetrack gates lifted ready to' move the car in the direction of the arrow; Fig. le, a scctional elevation of one of the cable-bolt holders; Fig. l5, a similar view showing a modiiicat-ionthereof; Fig. lil, a perspective of one of the cable-bolts; Fig. 1T, a similar view of a modified form ot' cable-bolt; Fig. 1S, a perspective view of the grain-shield to be connected with the lloor near the end of one of the tilting beams; Fig. 19,2111 enlarged sectional elevation of the lower part of the elevater-shaft with the cage therein and of the wagon with the rear portion of the box broken away, showing the grip-block oi' the elevatorcage cable attached thereto ready to hoist, and the wagon shown by dotted lines as just passing through the cage when the car is in the pit; Fig. 20, a diagrammatic view of a scale-platform, showing its location in the elevator-shaft and ihe connection with the weight-bea1n; and Fig. 2l, a transverse section through the car and floor of the cage when the latter is opposite the dumping-Hoor and showing the steady-pins and means'for holding the car from rolling on the cage.

The elevator-building is fram ed in any preferred manner, the studding l, joists 2, caps 3, rafters 4l, cupola 5, and ventilatoiframing 6 all joined together and covered with suitable material, a grainbin door 7, supported upon inclined beams S, extending entirely across the building at such height as to leave headroom for a team and driver at its middle point and inclined at a suitable angle to discharge the grain at one side of the building adjacent to the railroad-track 9 through discharge-spouts l0, and a du1nping-floorl1(see Figs. 2, 3, and 4) extends across to the caps 3 of the framing, the building being divided lengthwise into an equal number of compartments or bins 12 ateach end thereof, with an intermediate transverse passage 13, which extends from the bottom to the roof of the cupola and ventilator-framing 6. A lateral wing 14 provides a large storage bin or bins 15, the roof of which is coextensive with that of the main building, and also carries an extension of the transverse cupola and ventilator, and the transverse passage 13 of the main building extends through it at the top or dumping floor of the building. A dumpingtrack 1G, as shown in Figs. 1, 2, and 3 of ,the drawings, passes centrally through the length of the building` and intersects a slightly-elevated cross-track 17 in the transverse passage 13, the planes of intersection being fitted with vertical corner-posts 18 of an elevator-shaft 19. The elevator-shaft at the first floor is located in the line of a longitudinal hauling.

track or floor 20, which extends through the building beneath the dumping-track and is open at each end to allo7 grain-wagons to pass into the building at one end and out at the other. Two of the corner-posts 18 have longitudinal ratchet-plates 21 hinged thereto at their ends, as shown in Fig. 7, to fold from one side to the adjacent side of the said posts and enga-ge with 'spring-actuated dogs 25, secured to the cage-frame 25 of the elevator in a well-known manner, to provide a safety attachment to prevent the accidental fall of the loaded car while being lifted in the shaft, the said plates 21 being folded to the adjacent side of the posts to be out of the way of the cage-dogs when the unloaded car is lowered. r1`his is a great advantage and safeguard when the grain is elevated by the wagon-team and windlass, as Athe car may be stopped at any required height without pulling back upon the hoisting apparatus and team should it be convenient to stop at any time.

The elevator-cage 22 has a frame formed of corner-posts 23, a set of cross end bracing24 below, and a double set of similar cross-bracing 25 at the upper end of the cage connected by diagonal bracing 2U, thus formin ga trussed box-frame of great strength at the upper end of the elevator-cage, which will allow the cage when heavilyloaded to be lifted with perfect security.

The cable 27 passes over pulleys 28 in the roof-framing and extends downwardly to a small barrel 29 of a differential hoisting-drum 30, and is wound thereon to raise and lower the elevator-cage. The drum 30 is secured to a shaft 30X, supported in cross-pieces in the frame, and a larger barrel 32, upon the end of said drum 30, carries a second cable 33, which passes around it, then over an overhead pulley 34, down to the floor at one side, and thence crosswise to a pulley at the central line of the hauling-track.

The end of cable 33 is attached to a gripblock 35, provided with jaws 3G, which are made to engage with. the reach at the forward side of the rear wagon-axle. The jaws 3G comprise spring-steel plates 3G and heads 36h, which latter are normally pressed out by the action of the said spring-plates. A sleeve 37 embraces the plates 36 and is adapted to slide thereon toward the heads 36h to draw them together or to slide toward the block 35 to allow the heads to be spread apart by the pressure of t-he said spring-plates andV thus release the grip-block from engagement with the wagon reach or axle. A cord 38, attached to the sleeve 37, passes through a hole 35, formed in the block 35, to freely move therein, and is carried forward to the teamster upon the seat of the wagon 38, whereby the teamster may release the grip-block from the wagon by pulling upon the said cord 38 when the car has been raised to its full height in the elevator without the teamster leaving his seat, as shown in Fig. 19.

The cage and elevator-car and cable are balanced by counterbalance-weights 39 upon the end of a cable 40, which is attached to the upper end of the cage and passes over pulleys 41 on the roof-frame and moves with the weight up and down in the transverse passage 13 of the elevator.

A safety attachment of well-known construction, consisting of ratchet-bars 21 on the elevator-posts and spring-actuated dogs 25 on the cage near the upper end thereof, as shown in Figs. 2 vand 7, prevents the cageframe and car from falling in the shaft should the counterbalanee-supportin g cable 40 be accidentally broken.

The cables 27 and 33 for raising and lowering the cage are guided by a simple device located above the hoisting-drum 30, consisting of screw-shaf ts 44, carrying pulley-blocks 45 to lay the cables in regular coils upon the barrels 29 and 32, respectively. Sprocketwheels 30 and chains 30b upon the said shafts y44 gear with sprocket-Wheels upon the ends of the said drum-shafts to give to each of them and to their pulley-blocks 45 their required speed.

When the cage is at the bottom of the elevator-shaft and the car below the level of the hauling track or floor 20, atrap-door46,hinged .to one side of the pit at the said door-level,

is dropped down to cover the pit and allow the loaded Wagon to be drawn through the upper part of the elevator-cage and over the trap-door and pit, as shown by dotted lines in Fig. 19. The trap-door is then raised, as shown in Fig. 2, and the load is emptied into the car held upon the cage Within the pit. The wagon is preferably dumped, as shown in Fig. 2, by means of tilting beams 47, fitted in the hauling-floor 20, to be flush therewith when ready to receive the wagon, and journaled at 4S to parallel floor-beams 49, which hold the tilting beams truly in place while they are allowed to swing down at the end nearest the pit and carry with them the wagon, which is thus caused to dump its load into IIO the carwith-in the pit. A sheet-metal shield 50, having triangular sides and aconnecting end piece, is pivoted at the free ends or angles tothe sides ofthe floor-beams 49 to completely envelop the end of the tilting beam a7, and are adapted to be lifted up from below the hauling-licor 20 and held around the wheels and around the sides of the opening in the floor caused by the tilting" of the beams 4:7 to prevent the grain from falling through said opening instead of into the car. (See Figs. 2 and 1S.)

A scale 51 is placed in the bottom of the pit to fill the space in the door of the elevatorcage between the side bracing, and pins 52 upon the scale-platform pass up through holes in the floor of the elevator-cage a suitable distance to bear against the bottom and four corners of the car during the last few inches of movement of the elevator-cage within the pit and lift the car from the floor of the cage and transfer the weight thereof onto the scales.

The details of construction of the scale shown in Figs. 19 and 2O are immaterial, as any ordinary platform-scale will answer the purpose. A rocking shaft 53, having one arm connected with the weighing-levers of the scale and also having an arm connected by a rod 53 with the short arm of the weightbeaxn 5a, which latter may thus be located at one side of the elevator within convenient access of Athe elevator attendant, is clearly shown by diagram Fig. 2 A

.Af ter the grain has been weighed the wagon and tilting beams are pulled down to a level with the floor. The hoisting-cable 33 is then att-ached to the axle or to the reach in advance of the axle of the empty wagon by means of a coupling', consisting of spring-actuated jaws 36, attached to an eye-block 35, the normal position of the jaws being open, and a sliding sleeve 37 to embrace the jaws 36 to pull and. hold them together when attached to the reach, as shown in Fig. S. A cord 3S, secured to the sleeve, passes through the eye-block 35 and forward to the driver on his seat,as shown in Figs. S and 19, and when pulled tightly will draw the sleeve bach from the jaws toward the eye-block and allow the coupling to be disengaged and the wagon driven on without the driver having to leave his seat.

The dumping-car 57, carried by the elevator-cage, is constructed in a novel manner and is provided with wheels 58 upon its short sides, which project slightly beneath the bottom of the car, and also with wheels 59 at the longer sides thereof, which are placed above the wheels 58 a suitable distance, the wheels 5S to be used upon the main d nmping-track and the wheels 5) upon the longer side to be used upon the transverse tracks, as will hereinafter appear. The body of the car 57 is preferably made of sheet-iron, and the wheels are supported upon tubulariron axles, which extend through the body of the car. The car is pulled with its longer side toward the main dumping-track, and the bottom of the car is divided iifthe middle by a strip (l0, in order that the dnmljiing-doors may be conveniently arranged for operating from the ends of the car, and which will also be reduced one-half the length otherwise required. The doors 6l are supported at their ends upon separating triangular slats 62, connecting the divisionstrip (50 with the short sides of the car-body. The slats have two of their sides sloping upwardly into the body of the car and the remaining side flat and flush with the bottom of the car, the doors being hinged thereto in such manner that they will swing up against the bottom of the said slats GZwhen said doors are closed and hang vertically when open to provide a clear unobstructed space between each door for the free passage of the grain from the car when it is dumped.

The doors are arranged in two sets, extending from side to side, and are each connected at the bottom with a cross-strip 68, held thereto by a staple 6l, and a latch-bar 65 extends the entire width of the car beneath the cross-strips 63 to lift and hold the cross-stri ps G3 closed. A side latch-plate 66 is secured to and extends up each of the sides of the car and is flanged outwardly at its ends to engage with swinging latch-levers 67, which are intermediately pivoted at each of the shorter sides of the car and at the central line thereof. The upper end of the latch-levers engage beneath the flange of plates 6U, and the lower end of said levers is provided with a frictionroller (5S, which strikes against an adjustable stop to dump the car. as will hereinafter appear. The doors are all thus held firmly against the slatted bottom of the ear by the upper end of the latch-lever, and when the latter is removed the doors will drop clear of the openings by the weight of the grain in the cars. The weight of the rollers G8 and 68 at the lower end of the latch-lever tends to keep the upper end or latch of said lever pressing tightly against the under side of the flange of the side latch-plates 66. The latch-bar 65 extends across the full width of the carA and has cup-shaped socket-plates 69, near each of its ends, opening downwardly, which receive upwardly-pressing spring-pins 70, supported on bell-crank levers 7l, attached to a pushbar 72, which projects slightly beyond the floor of the elevator-cage. The pins hold the car stead y on the elevator-cage while it is being raised and lowered, and the end of the bar 72 will strike against a projection 72 at the bottom of the dumping-floor when the car has been raised to this height, and the pins 70 will be withdrawn from their sockets to permit the car to be rolled off from the elevator-cage. The bar 72 may be pushed in by an obstruction in the pit similar to the projection 72 at the bof-tom of the dumpinglioor to withdraw the pins 70 from their sockets when the car is in the pit.

rlhe bell-crank levers 7l and push-bar-72 are secured to the bottom of the floor of the cage and pass up through holes in the floor IOO IIO

IZO

thereof, andthe pins are drawn down to clear the car by the movement of the push-bar and may be lifted again bythe action of spiral springs 7 3, secured in the floor to surround the said pins.

lVhen the elevator-ca ge is lifted to the level of the dumping-track, the car is coupled to the free ends of cables 7 4 74, respectively, upon each side thereof and extending the full length of the du mping-track in opposite direction to the full length of the building, the opposite ends of said cables being wound around drums at the ends of said floor which extend across the track and are connected at one of their ends with a sprocket-chain 7 5, which passes over pulley-wheels 7 (i and extends beneath the floor of the grain-bins at one side f of the hauling-track to thetransverse passageway, and then around suitable sprocket-pulleys 77n and a crank-operated sprocket-wheel 77, located opposite the elevator-shaft, the said chains extending from opposite ends of the building to thus operate or move the car upon the dumping-track backward and forward in either direction.

The ends of the cables 74 7 4, respectively, are secured tocoupling-links 7S, one end of which has an eye 79 to receive the rope, and the other end of which has a head SO to engage with the coupling-block 8l of the car, and an intermediate conical portion 82 upon the link 7S is caught between jaws S3 upon weighted bell-crank arms S4, which serve to hold the end of the cable in position to be coupled with the car when the coupling-block 8l is brought in proper relation thereto. The coupling-block 8l has a vertical groove 8l and a horizontal transverse groove Sib, the former to pass up over the head of the link 78 to engage with the same when the cars are to be operated by cables 74 7 4 and the latter to allow the head of the link 7 S to be disengaged from said couplingblock 8l when a transverse cable is to be connected with the car, as will hereinafter appear. Cords 83X, connected to the crankarms SSXX, are carried down to the attendant on the lower {'loor and are used to open the jaws S3 and draw them down below the level of the iioor, release the cable, and permit the car to pass freely over the adjacent dumping-track. The jaws upon the opposite dumping-track remain closed and permit the link and cable to be drawn endw ise between them and serve to hold the said cable up and allow it to be drawn freely across the elevatorshaft with the car, and the neck portion S2 of the link is made larger at the coupling' end than'at the rope end to facilitate this operatien. The car may thus be moved to either side of the elevator-shaft therefrom by releasing the jaws 83 upon the side to which the car is to be removed and allowing the opposite corresponding jaws to remain closed.

Endless belts 85X below the floor at each end of the dumping-tracks, supported upon rollers and arranged closely to the inner sides of the rails 84 of said track, carry stop-plates 85, which intercept the rollers GS on the latchlevers and serve to release the dumpingdoors of the carto empty it. The horizontal endless belt-s 85X are operated by vertical belts S6, which are carried down to a crankhandled sprocket-wheel SGX within convenient reach of the attendant, as shown in llig. 2, and enable him from the lower floor to adjust the stop-plates S5 to any required position to dump the car when it shall come opposi-te the bin into which it is to be dumped. A similar operating-cable S7 and endless belts S8, carrying stop-plates 89X, for moving and dumping the car at any point upon the transverse storage-bin ydumping-track are employed. The cables 87X, however, overhang the car and have eyes SO upon the coupling-links to engage with pins 87, projecting upward from the sides of the car, and also have attened or oval necks S2, which, together with the clamping-jaws, hold the eyes of the links truly in position to engage with the pins of the car. The clamping-jmvs are also overhung and are pivoted to a crossbeam secured at its ends to the elevator-sha1' t guide-posts and are operated by a cord reaching to the lower oor, as in the jaws first described, as shown in Figs. l2, l5, and li'. The clamping-jaws, couplings, and cables are also connected with the opposite side of the car in the same manner and are used not only to draw the car back transversely to the elevator from the storage-bin, but also to move the car to the opposite side of the elevator, where it can be dumped into a chute 88, leading directly to a top opening of a grain-car S9 on the track or to a side spout 90, which will direetthe grain through the ordinary car-door.

In order that the car may be transferred from the main track to the cross or transverse track, it is necessary that the wheels 59 at the short sides of the car be lifted above the rails of the main track sufliciently to clear them and transfer the weight of the car onto the elevated wheels and rails at the ends of said car. This is done iirst by providing side rollers 91 on the car, which bear against side rails along the track and thus obviate the use of flanges upon the supporting-wheels. The elevator-cage is also provided with a lifting crossrail 17 at each end thereof, which meets the slightly-elevated rail of the transverse track when said cross-rail is lifted upon the elevator-cage. This is done by supporting the lifting-rail upon two plates 92, hinged at their upper ends to the cage-frame and having loops 93 at their lower ends to receive the ends of said lifting-rail, and allow the latter to be moved up and down in said loops. This movement of the lifting-rail is effected by spring-bolts 94 upon the iixed transverse track, which are pushed aside by the projecting ends of the lifting-rail as it ascends to a suflieient height to meet the transverse rail and to lift the side wheels and car sufcientl y IOO IIO

IZO

above the main rails, and the bolt-s are then pressed by their springs beneath the lift-ingrail. The cage is then caused to descend slightly and the weight of the car will rest upon the lifting-rail and the wheels will run upon the transverse track. A cord {lf-l, attached to the spring-bolts, will admit of their being withdrawn to release the lifting-rail and a-llow the cage to descend.

lVhen an increased storage capacit-y is required, two or more elevators may be employed which communicate with a side pit by means of a subway and track similar to the transverse dumping-track and arranged crosswise of the main du mping-track and of the hauling-track below the rails, being elevated in a similar manner above the main or direct rails 'upon the elevator-cage to engage with the transverse liftinfr-rail of the caire when the elevator-cage descends to the bottom of the elevator-pit. The lifting-rail is brought in Contact with a transverse rail 95, supported upon arms projecting upwardly from a scale at the bottom of the pit, which litt-s the rail and car when the cage descends the last fewinehes of its movement and throws the weight upon t-he scale.

The lifting-rail hereinbelore described is suspended by hinged slotted plates from a rod located above the car and supported on the corner-posts ol? the elevator-cage,and a springactuated locking-bolt 96 is connected to a cord 07, which passes through an eye 9S on the lifting-rail plate U2, and through a fixed eye 97, fastened to the building, and extends to the lower floor ot the elevator. By this means the swinging plates and lifting-rail maybe first released by drawing the bolt and then swung up out of the way of the car when the latter is to be moved by the cable upon the main dum ping-track.

The car is first placed in the d uniping-pit when two or more elevators-are connected therewith7 and after being iilled it is rolled through the subway onto one of the elevators and hoisted to the dumping-licor and handled as hereinbefore described.

lVhen a double elevator is employed, the bins may be arranged as shown in Fig. Li, a double iioor being employed at sufficiente-ngle to allow the grain to movefreelyover both floors to the discharge-pipe at the side of the elevator building.

By means of my improved appliances an elevator may be operated with less expense than where either separate horse or steam power is employed for operating it, as one man may handle the entire apparatus with the assistance of the driver who hanls the grain to the elevator.

rihe weighing, transferring, and distribut` ing facilities are so arranged that they are all reached from a central point, and the grain may be continually weighed separately in a car or box under constant and never-varying conditions, which will insure great accuracy in handling the grain.

The various bins and cross-bins, reached by direct and cross tracks and by subways and double elevators, lwill admit of unlimited extension in any preferred or convenient direction from the central hoisting-shaft and haulway and the greatest possible advantage is. obtainable l'or handling and separately storing every kind of grain brought to the elevator.
